Ultrasonography is a valuable tool for the evaluation of neoplastic lesions in the dog and there is a growing interest in the use of this technique for the stadiation of canine mammary tumours. An accurate assessment of small sized nodules facilitates the stadiation of the mammary lesions and helps the clinician in the choice of the most indicated surgical therapy. The aim of this study was to identify those ultrasound criteria that may be useful in discriminating between benign and malignant lesions of small size (diameter smaller than 2 cm). Sixty-two nodules, < 2 cm in larger diameter, belonging to thirty-five bitches presented between January 2012 and February 2014 were evaluated. Tumours were observed by conventional ultrasound and assessed for: shape (regular-irregular), limit (defined-ill-defined), margins (regular-irregular), echogenicity (hypoechoic-isoechoic-hyperecoic), echotexture (homogeneus-heterogeneus), presence of hyperecoic halo, distal acoustic enhancement or shadowing and surrounding tissue alterations. Among the alterations in surrounding tissues, the disruption of the glandular tissue and the increase in echogenicity of the peritumoral tissues were assessed. Thereafter, bitches were subjected to mastectomy and nodules were evaluated histologically. None of the ultasound criteria considered in the current study showed a statistically significant relation with malignancy, except for the presence of alterations in the tissue surrounding the nodules. According to our results, this characteristic may indicate malignancy, however its subjectivity may affect the applicability in clinical practice. In conclusions, conventional ultrasound in bitches had a limited ability in discriminating benign and malignant mammary gland neoplastic lesions of small size (diameter?<?2 cm).  相似文献

Stress and Humoral Innate Immune Response of Gilthead Seabream Sparus aurata Cultured in Sea Cages     

Fulvio Salati  Giulia Angelucci  Alessandra Fenza  Adele Meluzzi 《Journal of aquatic animal health》2016,28(3):166-172

Innate and acquired immune responses of Gilthead Seabream Sparus aurata was studied under normal culture and short-term stressful conditions for 18 months in offshore sea cages in Alghero Bay, Italy. Every 45 d, 50 fish were sampled and divided into two groups: fish in the first group (normal culture conditions) were bled after harvesting; fish in the second group were put into a tank under stressful conditions (crowding and confinement) and bled after 2 h. Innate humoral immunity, such as complement-like, hemagglutination, and lysozyme activities, was determined in the sera of both groups. Pathogen challenge was not performed, but the specific humoral immune response was assessed against the most common pathogens affecting cultured fish in Sardinia. Stressed fish, compared with the control, showed a lower lysozyme activity against Vibrio (Listonella) anguillarum, which was not clearly correlated with temperatures. Complement-like activity differed between the first and second half of the study and, at the end of the trial, a slightly higher activity was recorded in the controls than in the stressed fish. Hemagglutination activity was mainly higher in the stressed fish than in control fish. Confinement, crowding, and cold water temperature caused decreased lysozyme activity in short-term stressed Gilthead Seabream compared with those reared normally. The specific humoral immune response, against V. anguillarum, Tenacibaculum mesophilum, Enterococcus Seriolicida, and Aeromonas sobria, fluctuated during the rearing period, particularly during the first year of culture.

Nitrogen and carbon mineralisation of leather meal in soil as affected by particle size of fertiliser and microbiological activity of soil     

Maria?Teresa?Dell'AbateEmail author  Anna?Benedetti  Alessandra?Trinchera  Daniele?Galluzzo 《Biology and Fertility of Soils》2003,37(2):124-129

Carbon and nitrogen mineralisation of leather meal fertilisers were studied in two soils characterised by different respiration activity. Both C and N mineralisation were highest in the most active soil, and when leather meal was added as a powder rather than as 2- to 4- and 4- to 6-mm particles. Fast and slow soluble N pools were determined after extraction with cold water and with hot buffer, respectively. The N remaining after the second extraction with hot buffer was named slow-release N. The percentage of slow-release N rose as the size of the applied leather meal particles increased, whereas fast soluble N was highest in the coarsest (4-6 mm) fertiliser.  相似文献   

Optimization of a pilot-scale process for producing lupin protein isolates with valuable technological properties and minimum thermal damage     

D'Agostina A  Antonioni C  Resta D  Arnoldi A  Bez J  Knauf U  Wäsche A 《Journal of agricultural and food chemistry》2006,54(1):92-98

This paper describes a pilot process for obtaining protein isolates from white lupin seed with improved water solubility and technofunctional properties as well as reduced thermal damage. After a careful optimization of the process parameters, two valuable food ingredients were prepared: lupin protein isolate type E, with a useful emulsifying capacity, and lupin protein isolate type F, with a high capability of foam formation and stabilization. The spray-drying process was particularly critical for inducing some thermal damage, but a careful selection of the conditions permitted ingredients having only marginally impaired lysine bioavailability to be obtained. The reproducibility of the protein extraction process was tested on two different lupin varieties.  相似文献   

Supercritical CO2 extract of Cinnamomum zeylanicum: chemical characterization and antityrosinase activity     

Marongiu B  Piras A  Porcedda S  Tuveri E  Sanjust E  Meli M  Sollai F  Zucca P  Rescigno A 《Journal of agricultural and food chemistry》2007,55(24):10022-10027

The volatile oil of the bark of Cinnamomum zeylanicum was extracted by means of supercritical CO2 fluid extraction in different conditions of pressure and temperature. Its chemical composition was characterized by GC-MS analysis. Nineteen compounds, which in the supercritical extract represented >95% of the oil, were identified. (E)-Cinnamaldehyde (77.1%), (E)-beta-caryophyllene (6.0%), alpha-terpineol (4.4%), and eugenol (3.0%) were found to be the major constituents. The SFE oil of cinnamon was screened for its biological activity about the formation of melanin in vitro. The extract showed antityrosinase activity and was able to reduce the formation of insoluble flakes of melanin from tyrosine. The oil also delayed the browning effect in apple homogenate. (E)-Cinnamaldehyde and eugenol were found to be mainly responsible of this inhibition effect.  相似文献
